To all whom it ntay concern:-

Be it known that I, CHARLES N. NEW- COMB, s citizen of the United States of Americe, residing atWest Pslmbeach, inthe county of Dede and State of Florida, have invented new and useful Improvements in Suction- Dredges, of which the following is s specificstl%l. V his invention relates to improvernonts in suction-drcdges of that class rovidcd with a hollow rotary dredging-whee carrying buck ets or scoops to. other the sand. silt, gravel, V clay, muck, or ot or materiel to he excsvsted the wheel Figure 1 1s a top plan View, artly in horizontal section. of a portion 0 the hull of a drcdger embodying my improved excavating mechanism, showing in dotted lines certain features omitted by the plane of section. Fig. 2 is a vertical longitudinal section on line 2 2 Pi 3 is a view in elevation of a ortion of the ollow axle or stationary mefnr. r of the cxcavstingwhcel. Fig. 4 is a. longitudinsl section through a portion of the complete wheel, taken on line 4 4 of Fi 5.

Fig. 7 is a. perspective View of one of the-buckets em loyed therein. Fi 8 is a perspective View 0 a portion of the w eel, showing s fur ther modification in the construction of the hollow shaft and buckets. Fig. 9 iseplan vicw of the some with all the buckets removed. F" 10 is a cross-section through the buckets part of the wheel shown in 8. Fig. 11 is a. detail section showing the construction of a. cutting edge for at cost bucket. 7

Referring now more particularly to the had to the accompanying drawings, the numeral 1 designates the hull of a tire e of the described type on which is supported an engine 2, which drives the engins or power shaft 3, the fly-wheel 4 of which has a. crank connection with e pitmanrod 5 which sctuates the piston of a. suction- "ump 6, having an outiet or discharge pipe 7. Rhe pump 6 is in communication with a suctionipe connected with the excavating whee said pipe consisting of a. stationary section 8, provided or connected at Its forword end with a. suctionchsmber 9, and a movable section 18, pivotelly mounted on a counter-shaft 11, journsled-in suitable beerings on the hullend extending through said suction-chamber, whereby the pipe-section hull may swing freely in a vertical plane with the excavating-wheel. serves as a drive-shaft for the excavatingwheel, receives-motion fromthe on ino shsft 3 through the mediuznof a spree et-chein 12, engaging sprooketswheels 13 end '14 on said shafts. f

Pivotslly mounted upon the ends of the shaft 11ers supporting beams or arms 15, forming at vcrtioslly-swmging frame to sunport'the excavating-wheel, which letter 1s 10, which projectsbsyond. one end of the Theshsft ll, which sup aortcd'upon the outer ends of said arms and is adopted to be balanced or controlled by chains 16, secured at their lower ends to thearms a'nd passing upwardly and rear werdly over supportinj pulleys or sheaves 17 carried by e suitab e framework 18, the

chains leading back to a suitable point to be operated in any preferred nsnner to control the excavating-wheel in its operstions. l The excavating-wheel comprises in its construction s. stationary member 19, consistin of 3 pi e orcylinderheving its ends clos and suitably mounted in the forward ends of the srrns 15 and firovided at suitable intervsiis throu hout itslcngthwith openings or ports 26, t rough whic the material taken 7 the buckets or scoops feeds thereinto.

member or pipe 19 forms an the hollow shafts or rotary o stations axle on wluc members '21 of the wheel are revolubly mounted and serves sis s suction-box from winch the air is exhausted by the action of the suction-pump 6 to effect the drewel of the excsveted'matcriol therein and its discherge therefrom, The suction-pipe section 10 is connected at its forward end with the can tral portion of the hollow axle 1 9 and is=adapted to swing vertically with the wheel through its ivotal connection with theshaft 11.

he hollow shafts 21, of which two areems ployed, surround the hollow axle 1 9 on oppo-, site sides of the suction-pipe section and:

are each composed of a series of sleeves 22,

having their adjacent endportions arranged 2'0. section 22 is provided at one side with arrin- -let-port.27,and a bucket or scoop 28 integral therewith,..each scoop comprising a curved .bddy portion 29, having a forward, cutting "edge .30 and'side pieces 31, disposed on oppo- QSHSitG- sides of" the inletopening 28 and 1ntegrally connected withthe flanges 23 ,the rear end of the body ortion bei integrally con- .nected .with the ody of the s eeve at the rear 'ofthe ort 27 in the direction of revolution okofithe aft. The sleeves or sections of each ,hollow, shaft are so arranged and connected as to position the scoops or buckets at different points aroundthe circumference of the shaft or at different points in the path-of -rotation thereof, so as. to, in effect, give a ,s iral arran ement to the buckets in'order it at they Md 1 act alternately throu bout the series in the revolution of the sha tbrtake supthe material to be excavated. The ports oi2O in the hollow axle 19 are closed by the 1 sleeve-sections untilthe ports 27 ofthe tter come in registertherewith, thus allowing-the -material taken ,up .bywthe. buckets to. pass '.therefrom.into;-the hollow shaft and to dis- 451 chargetherefrom throu h the suction-pipe -10. iBy sIpirall disposinglt e bucketsintt emanner escri e a sing ebucketiat a time will communiclt through re teringv arts with ,the axle 19, sc-thatall o ,the suction power 7 5c .will be exerted to extract the material therefrom, a feature of obviousadvantage lover prior constructions inwhicha the material is simultaneously extracted from a pl-urality of buckets, inasmuch as a stronger suction ac- 5 sution for the extraction of; the material from sithe bucket is obtained. I The hollow shafts revolve rearwardly, and the cutting edges, of 'the buckets successively come into contact with and cut away and shoe -up the-,mate- 6o. rial, which is drawn rearwar 1y through the suction-pipe and discharges through the out- Jet-pi e 7. Motion is communicated from :the rive-shaft 11 to the hollow shafts .through themedium of sprocket -chains 32,

l sleeves. and 'a ge fa or rivets :wh-ich secuiejthenflanges of the adjacentf sleeves together. This construction permits otithe removali at .the bucket pro er -=ther modification wherein the hollow-shaft .the ports--20 in; the hollow axle-19. The

while the sides thereof are forme with rear-- ,Wardly-extending curved arms 34, having rows of apertures 35. The sides of the body portiomand arms 34 are sefgmentally curved the she t 5 .to conform -tQ :the. shape 0 -sleeve,

The buckets or.- scoops disclosed in this invention correspond substantially in construction with that disclosed in Figs. 6 and 7,except-thatthe curved arms 34,insteacl of. beingproyided withtthe apertures '35, are formed with; latersllzifprojecting flanges. 38, in which theperfora ions areformed on :the passage of bolts.or,.-rivets 39 toafasten the same to:v the shaft, hich-latter is provided with rows of periorations 4!) for the passe. e v of said bolts or rivetsrand-which are proper y ,arran ed. relative rtottheresplective,ports to accor withgthe positions of t e ports, so-that thebuckets-may be properly fastened in position to. regiatentherewith. ilmeach ofi the constructions described the boo portion of the hollow shaft operates s velve to close the orts 20 in the hollow shefr 1% until the hueet-openings in the hollow shaft come into register therewith, the hookers or their spiral arrangement snooessively discharging in the course of rotation of the shaft into the hollow axle l9 7 It is preferred in pra otioe to form the hollow shaft and hooker-s of wrought-slash in which event the cut-ting-surfaoes 3% ol the buckets may he formed by beveling the ll 6 ward edges thereof in such manner"; adagat them to be conveniently sharps when required.
